Abstract (en)
[origin: US4313067A] A sensor-integrator utilizes a light sensing diode directly connected to the inputs of an operational amplifier. The operational amplifier forms part of a dual-slope integrator and directly integrates the current generated by the light sensing diode thereby eliminating the need for preamplifiers and diode switching circuitry.
